The bearing of the is extended a tongue 18 on whichare formed forwardly diverging spreading ribs 19. A

short-longitudinal slot 20 is formed in the the housing 8 through opening 10 and secured to a rock shaft 26 journaled in one side of the housing 8. As shown particularly in Figure 3 the bearing of this rock shaft is provided with a steam tight packing 27. To the outer end ofthe rock shaft 26 is attached an operating lever 28 having a short 7 arm 29 in which is formed a longitudinal slot 29'. This lever can be actuated by any suitable means adjacent thereto or extending to 1 point remote therefrom.

Slidably mounted in the upper section 1 is a tapered valve 30 the inclined lower face of whichis parallel with the upper face of the seat 13 and extends thereover. This slide valve is supported by guide ribs31 or other suitable meansprovided for that purpose and has alongitudinal slot 32 in theinner end thereof communicating with a transverse groove 33 formed in the top-of the valve. Movably mounted in the slot 32 is a link or connecting rod 34 having a head 35 movably mounted in the transverse groove-33. This link or connecting rod is pivotally attached at 36 to a crank arm 37 extending throughthe opening 9 and secured to a rock shaft 38 jourrock shaft is provided with a packing 39 to prevent leakage and the outer end of the shaft has an arm 40 secured theretoand pro vided with a longitudinal slot 41.; A connecting pin 42 is adjustably secured in either slot 29' or slot 41 and is adapted to slide free ly in the other one of these two slots. Thus when lever 28" is oscillated motion'will' be transmittedtherefrom through pin 42 to the arm 40 so thatthe two shafts 26 and 38 will be rocked simultaneously. By adjusting the pin 42 longitudinally of the slots the relative movement of the shafts 26 and 38 can be varied as will be obvious. e

The parts are so located and proportioned that when lever 28 is in one extreme position the two slide valves 17 and 30 will bear tightly against the active faces of the respective seats 14 and 13, thereby positively preventing leakage of oil from the section 1 and of steam from the section 4.. By shifting lever 28 in the opposite direction the two shafts26 and 38 will be simultaneously rotated thereby to withdraw the valves 17 and 30 from their seats. promptly so as to escape between valve 17 and seat 14 and past the lowerends of the ports 16 thereby'creating a downward suction through the ports. At the same time oil Thus a sheet of steam will be released delivered to the section 1 will be free to flow between valve 30 and its seat 13 and will be sucked downwardly by the escaping steam through the ports 16'into the space between tongue 18 and seat 14. This space, indicated at 43, constitutes a mixing chamber where the steam and oil are thoroughly 7; commingled before the mixture is delivered at a jhigh velocity over the spreading ribs 19. Oh.- viously this mixture of oil and steam will be highly infiammablelia'nd by properly adjusting the pin 42 so as to produce correct'relative movement of the two valves, the correct mixturesfor producing the best results can be obtained. r

It will be noted that steam underboiler pressure can be used and as the valves move bodily, away from their seats there" is no chance for foreign substances to clog the burner.".lnsteadthey will be blown out by the pressure within the burner. Furthermore, as the fuel will be thoroughly atomized 7 before it can escape from the burner all danger; of the delivery of'unatomi ze d fuel is eliminated and, consequently, there is'no danger of'the formation of carbon on the splash wallorthe wall of the fire box. When the burner isnot to be used the valves can'be shifted tightly against their seats, thereby preventing leakage of oil or steam.

While thefribs 19 may be formed on the end portion of the tongue 18 they can, if'preferred, be made on a part separate therefrom.

What is claimed is I 1. A burnerincluding a housing, a parti tion therein, means for directing oil and steam into the housing at opposite sides respectively of the partition, v inclined valve seats on the opposite sides respectively ofthe'partition, tapered slide valvesat opposite sides of the" partition movable into and out of contact with the seats, an actuating element, and adjustable means shiftable by the actuating element for simultaneously moving the valves at predeterminedrelative speeds. g r

2. A burner inclu'dlnga housing, a parti tion therein, means for dlrecting oil and steam into the housing at opposite sides respectively of the partition, inclined valve seats on the oppositesides respectively of the partition,

tapered slide valves at opposite sides of the partition movable into and out of contact with the seats, means for simultaneously-actuating the valves, and a spreading means adjacent the outer end of one of the valves in the path of fuel delivered past said valve. 5 3. A burner including a housing, apartiinto the housing at oppositesides respectively of the partition, inclined valve seatson' the oppositesides respectively of the partition, tapered slide valves at oppositesidesof the partition movable into and out of contact with the seats, there being ports for maintaining communication between the valveseats, said tion therein, means for directing oil and steam the outlet end of each of said spaces, said,

each section opening into the adjacent portion ofthe section, operating means within each houslng, an mchned valve seat on each 1 side of the partition partly closing one end portion ofthe section in which itls located,

the other end portion of the s'ectionbeingj closed, a tapered slide valve in each section movable into and out ofcontaotwith the ad-'1 jacent valve seat to shut off fiow'of fluid and to permit flowfithereof, respectively, and a connection jbetween each Valve and theoperating means in the housing in thesection in which the valve is located.- 7

"5. A burner including opposed sections closed at one end and open at the other end,

housings on'the respective sections opening q thereinto and apartitioninterposed between 'and' secured to the section for dividing the interionof the housing into separate fluid;

receiving spaces, of an inclined valve seat at valve seats being mounted onopposed faces respectively of the partition, there being ports extending through the valve seatsfor "establishing communication between the f spaces at opposite sides ofthe partition, 21

i slidevalve cooperating with each valve seat and movable thereagainst to close the port, and operating mechanisms within the housdings andsections for actuating the respective slide valves.

, In testimony that I claim the foregoing as, my own,.Ihave-hereto' affixed my signature.
